Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully convey behavioral traits. It discloses a key behavior (does not attach the script) and states that it returns validity as data, which implies non-destructive operation. However, it does not mention error handling, require file existence, or potential side effects, leaving some gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
